This work presents the analysis of data collected by Universidade Federal do Rio Grande do Norte and State Public Prosecution Office experts concerning to current situation of liquid fuel resale stations, its forms of storage and its technical apparatus for the performance of primary functions (supply of vehicles) and secondary (car washing, storage of used oil, oil change etc.). The data presented were analyzed in the setting of the city of Natal (RN) and considering its characteristics, potentialities and weaknesses. Thereafter, it was discussed liquid fuels resale pollution potential in the city and legal provisions directed to implementation of Green Seal. The discussion involves three agents: environmental, legal and technical ones, applied to all 110 resale fuel stations which were analyzed

The implementation of local geodetic networks for georeferencing of rural properties has become a requirement after publication of the Georeferencing Technical Standard by INCRA. According to this standard, the maximum distance of baselines to GNSS L1 receivers is of 20 km. Besides the length of the baseline, the geometry and the number of geodetic control stations are other factors to be considered in the implementation of geodetic networks. Thus, this research aimed to examine the influence of baseline lengths higher than the regulated limit of 20 km, the geometry and the number of control stations on quality of local geodetic networks for georeferencing, and also to demonstrate the importance of using specific tests to evaluate the solution of ambiguities and on the quality of the adjustment. The results indicated that the increasing number of control stations has improved the quality of the network, the geometry has not influenced on the quality and the baseline length has influenced on the quality; however, lengths higher than 20 km has not interrupted the implementation, with GPS L1 receiver, of the local geodetic network for the purpose of georeferencing. Also, the use of different statistical tests, both for the evaluation of the resolution of ambiguities and for the adjustment, have enabled greater clearness in analyzing the results, which allow that unsuitable observations may be eliminated.

It is known that the urban environment modifies the energy balance between the surface and the atmosphere, causing changes in temperature, relative humidity, among other things, opening the way for studies aimed at urban climatology. Based on the theme of urban climate, this research focuses on the city of Assis, located west of São Paulo. The generation of urban climate is a result of various factors, among which stand out: the use and different land use, the thermodynamic properties of buildings, number of buildings in the urban, socioeconomic activities, etc.. In general, this increases the temperature and reducing relative humidity, providing thermal discomfort. The rural environment is used for comparison studies to this theme by presenting different characteristics in relation to the structure, morphology and urban functionality. The main objective of this study is to determine the characteristics of temperature and humidity environments with the habits and occupations of the different soils in winter, at night, one inserted into the urban fabric of Assis and the other in the rural environment, to verify for evidence of changes in climatic elements because of urbanization. To collect the data will be used mini automatic weather stations that record data on temperature and humidity. For analysis of the results will be made between the data obtained in the city and the countryside, developing graphics application using Excel to tabulate the data. It was found that there were differences in the thermo-hygrometric data collection points, showing a specific urban climate in the city of Assis

Most of the proposed key management protocols for wireless sensor networks (WSNs) in the literature assume that a single base station is used and that the base station is trustworthy. However, there are applications in which multiple base stations are used and the security of the base stations must be considered. This paper investigates a key management protocol in wireless sensor networks which include multiple base stations. We consider the situations in which both the base stations and the sensor nodes can be compromised. The proposed key management protocol, mKeying, includes two schemes, a key distribution scheme, mKeyDist, supporting multiple base stations in the network, and a key revocation scheme, mKeyRev, used to efficiently remove the compromised nodes from the network. Our analyses show that the proposed protocol is efficient and secure against the compromise of the base stations and the sensor nodes.
